Central Processing: Primary Server Bank

"Welcome to the Mess Hall!"

- Sabaoth

Central Processing: Primary Server Bank (called Central Server Banks: Primary Server Bank in Doom 3: BFG Edition and on the original Xbox version) is the twenty-third level of Doom 3. The player fights the third boss, Sabaoth, the demon transformation of Sergeant Kelly.

Summary
The marine enters the Primary Server Bank and faces a host of monsters almost immediately while the demonified Sergeant Kelly taunts him over the loudspeakers. After clearing out the CPU complex, the marine goes to the Central Bridge which is positioned within a massive chamber leading to multiple sections of the facility. The marine must reach Central Processing where Sergeant Kelly is located. However, he first needs to find Steve Tooloose's PDA to gain access.

The marine heads to the Server Bank and recovers Tooloose's PDA. There is also an informational video on the BFG 9000. The video reveals that small arms ballistics can cause the BFG projectile to detonate prematurely.

The marine makes it to Central Processing, where he finds Sergeant Kelly waiting for him. The Sergeant has been transformed into a hideous tank-like monster called Sabaoth. He has also integrated Campbell's BFG into his body, and uses it against the marine. The marine, however, uses his newly acquired knowledge of the BFG's weaknesses against Sabaoth. After an extended fight, the marine defeats his former commanding officer, and takes Campbell's BFG for himself. He then heads down into Sublevel 9 and takes the elevator to the next level: Site 3.

Enemies
The enemy count on Nightmare is the same as on Veteran. There are no changes in enemy amount in the BFG Edition. * Wraiths in this level are spawned by the arch-viles, thus their amount can vary. Here only the number of distinct spawn points is shown. ** If playing on Nightmare difficulty, one revenant cannot be killed - it would normally appear when a medikit in the Main Storage room is collected, but there is no medikit on Nightmare. The revenant can still be heard behind the wall, but there is no way to make it emerge.
